    Listen to this Article

    Ultraviolette Automotive’s F77 is currently the most expensive and most powerful electric bike on the market today. We stack up both variants of the F77 against two entry level sportbikes – the BMW G 310 RR and the KTM RC390. 

    Ultraviolette F77 vs rivals: powertrain and acceleration

    0-100 kph8.3s (claimed)8.0s (claimed)7.36s (Sport) 9.60s (Urban)5.85s


    While both variants of the F77 comfortably outclass the torque figures of the BMW G 310 RR and the KTM RC 390, in the sprint to 60kph and 100kph, the KTM is quicker than the F77. Even the BMW G 310 RR is only marginally slower to 60kph than the top-spec Recon variant and comfortably beats the F77 to the 100kph dash. The numbers used for the BMW and the KTM are our in-house performance tested numbers.

    In terms of hardware, all bikes here are evenly matched, but the F77 is the only one to feature preload-adjustability at both ends. The RC 390, however, is the only bike here to feature rebound adjustability.

    Ultraviolette F77 vs rivals: features

    Both variants of the F77 e-bike come equipped with features such as smartphone connectivity for the TFT dash, enabling turn-by-turn navigation, music playback and notification alerts. Features such as crash detection, geofencing and vehicle location are also part of the package. The F77 has three ride modes – Glide, Combat and Ballistic. One caveat here is that the Ballistic mode can only be used if the battery is at or above 70 percent charge.

    The BMW G 310 RR is equipped with four riding modes – Track, Sport, Urban and Rain – with the former two giving you access to full power and the others mellowing it down.

    The KTM RC 390 is equipped with a bi-directional quickshifter, a feature you’ll have to pay at least thrice its price to get on another ICE bike.

    Ultraviolette F77 vs rivals: weight and dimensions

    Fuel capacityNANA11 litres13.7 litres
    Ground clearance160mm160mmNA153mm

    As can be seen from the table above, the F77 is a much heavier bike than its ICE competition. In fact, the Recon variant weighs 35kg more than the KTM RC 390! That weight penalty does decrease on the Original variant but even that, at 197kg, weighs more than a Royal Enfield Classic 350.

    Ultraviolette F77 vs rivals: price

    F77 OriginalF77 ReconBMW G 310 RRKTM RC 390
    Price (ex-showroom, Delhi)Rs 3.80 lakhRs 4.55 lakhRs 2.90 lakhRs 3.14 lakh

    Priced between Rs 3.80 lakh-4.55 lakh, the F77 e-bike is substantially more expensive to purchase than the BMW G 310 RR and the KTM RC 390, and while it does have a fair few features, it can’t really match them in terms of performance. Also, considering that a widespread charging network is yet to be established in India, the F77 can’t match the widespread usability of the other two either.

    Long term maintenance and running cost over a period of 3-5 years also should be considered, IMHO. Thrill seekers mostly head to the nearest hills and back, so range upto an extent can be undermined. I am sure you can't do globe trotting in a RC390, you will break your back much before running out of fuel. Not everyday you see a motorcycle that can challenge something like the KTM in electric segment. More importantly F77 is electric and usually will feel like a lot more powerful than an equivalent ICE powered bike. For example:- we have cars which are EVs with the same power figures and carry 1700kg payload and feel like 100bhp ICE cars, just imagine the feel you get with a same powered bike. Just comparing specs on paper might not tell the whole story.

    The Mahindra XUV 300 facelift will be called the XUV 3XO. Should more brands rename models for facelifts?

    Yes, it could give new life to a slow-selling car



    Yes, but only if there are significant changes



    No, it's confusing and dilutes the brand name



    No difference, the product speaks for itself
